After the flood of new releases that marks the return to routine, this period defines which books establish themselves as genuine best sellers and which are just flashing through.
The 10 most notable titles during the second week of September 2025 in Spain are far from a homogeneous list; the tastes of Spanish readers reveal a fragmented and dynamic market, which continues in this second week, dominated by loyalty to established authors, the rise of new genres, and a notable diversification in nonfiction.
